Time for a tune up

[Danzigman]

Is it best to stick with OEM plug wires or go aftermarket? I have read a few articles and now I am more confused than before I began. The Tahoe has 140k on the clock with the original wires. I replaced the plugs several years back with rapid fires. What is the interval of change on plugs in these modern engines? What about 02 sensors? Do they need to be replaced before failure? Any other tune up tips you can share I would appreciate it.

Plugs and wires are listed for 100k. Most guys stick with OE delco plugs. Upgrade the wires. Taylor or VMS 10.4 mm are probably your best options. The o2 sensors can get lazy as they age. A live data scanner is the best way to check. Cleaning your MAF and throttle body is a good idea while you're playing in there.

i would get Taylor wires and either recommended delco plugs or ngk plugs. you dont need anything besides recommended plugs. the wires i recommend only because of the quality i see with Taylor wires.

02 sensors are rated for 100k, if money isn't a issue I would recommend doing all 4 at once, and keep on truckin, rockauto or amazon will probably have your best prices

Anyone know the ac part numbers for the o2 sensors?

 

[NardDog]

Ditto on the MAF

This has been a very valuable link for me to get the starting point for part shopping.

I wish this one would show the professional series part numbers.

My Taylor wires arrived today. I bought the thundervolt 8.2 wires, they do not seem that empressive in the box. The boots seem short. These seemed like the street wire set. Is this what everyone is running?

I thought I got it to somehow one time. You can always cross it with Google or rock auto. I tend to buy OE line anyways most of the time. I HATE replacing parts with ones that aren't at least as good as what I took off.

No, 10.4. Look on ebay for VMS. The Taylor's I think are called Extreme.

Ok, I put the vin into the site and found the ac professional series part number of 213-2934. It shows this one for all four sensors.

Generally the professional series is better than the standard OE series. I know the pro water pump is the only way to go. Has anyone used the pro o2 sensors?

This is a commonly held misconception due to them naming it "PRO". A basic delco part would be the "advantage" line. You will notice that OE is always more expensive than PRO. I believe there is a reason for that and tend to stick with it. The delco lines are as follows:

Interesting I was told the pro was a step up... I better cancel that o2 order asap. I did send the 8.2 Taylors back to get the 10mm wires.

Yup, like that water pump you said. The pro is about $80, the OE is $125. The pro stuff is good. Most guys use it for most things without hesitation. There have been a couple times I've opted for it, as well. I would think the O2s are just such an item. Pro should be just fine.

The pro pump was specifically recommended over the oe unit. The research I did said it was an improvement as the oe’s were failing. This was two years ago I would guess. As for the o2, the oe has 2 part numbers and the pro only one, but if you read the reviews they state that the oe wires are sometimes to short when compared to the pro version. The pro version is pricer as well. Strange

I'm sure there are times when Pro is the way to go over OE as you guys are discovering. I don't remember the particulars but there are some things where only PRO is available anymore.

Oh great. I've got the OE pump in my garage.

No worries then about it failing where it is now....
